Legal Tech Firm Harvey Launches 'Harvey Tenet' Model Based on Kimi K3

San Francisco-based legal tech provider Harvey, whose high-profile backers also include Sequoia Capital and Andreessen Horowitz, said on Thursday that its new model, Harvey Tenet, was post-trained on top of the open-weight Kimi K3 base.

The company said the system achieved “state-of-the-art” performance in complex legal work.

Harvey’s pivot was “a great example of open-weight models” enabling developers to post-train systems on specific industry or corporate data for higher accuracy and lower inference costs, AI policy researcher Simon Hedlin wrote on social media on Friday.

Post-training is the process of refining a general-purpose base model with specialised data sets to excel at specific tasks.
